Recently, cumulants in these statistical distributions were widely taken as baselines to help us understand the experimentally measured cumulants, such the the cumulants of the net-proton, net-charge, net-kaon and net-\(\Lambda \)  [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}. To date, the studies of cumulants in BD/NBD have been up to the fourth order. It is found that the BD/NBD baselines can quantitatively explain the cumulants of net-charge, net-kaon and net-\(\Lambda \)  in experiment. The BD can also describe the fourth order cumulant of the net-proton number at \(\sqrt{s_{NN}}\ge \)  39 GeV. Consequently, it is also interesting to study the net-proton \(C_6/C_2\)  in BD.
